CASE STUDY Die Casting : 91% Pump Wear Reduction with a Polyol Ester (HFD) Hydraulic Fluid QUINTOLUBRIC® 888 The Challenge
The Benefits
An automotive parts manufacturer was looking to replace the water glycol (HFC) fire- resistant hydraulic fluids being used to operate their die casting equipment. The fluid being used:
With the use of QUINTOLUBRIC® 888, the results were:
ad the typical lubricating properties of water • Hglycol fluids
• Had unacceptable pump wear and pump lifetime The Solution To help improve operations, the manufacturer tested QUINTOLUBRIC® 888 polyolester (HFD) fluids as a potential replacement. QUINTOLUBRIC® 888 is a synthetic fluid that can be used in equipment designed for traditional mineral oil fluids and provides better performance than fluids containing water. In addition to fire resistance, the product provides excellent biodegradability and low aquatic toxicity, making it ideal for use where better environment protection is required. It is approved by FM Global as a less hazardous hydraulic fluid. QUINTOLUBRIC 888 is unique in the industry because the same product is available worldwide and it outperforms competitive products in fluid life with consistent performance. ®
• 91% wear reduction in the vane pump • 5 times longer pump life • Increased seal life by 2.5-3 times • Elimination of required fluid adjustments • Noise reduction in the pump and motor • Decreased power consumption by 5%. BEFORE WATER GLYCOL
